==Ownership==
 
{{table el|len=1 byte (0x1)|loc=0x1C|valrange=0x00-0xFF (bit separate, not a number value)}}
 
Each [[Binary#Bit|bit]] is a true false flag. The following list shows the [[hexadecimal]] of the bit paired with what happens when that bit is set:
 
* 0x01 = [[EarthBound:Ness|Ness]] can use
 
* 0x02 = [[EarthBound:Paula|Paula]] can use
 
* 0x04 = [[EarthBound:Jeff|Jeff]] can use
 
* 0x08 = [[EarthBound:Poo|Poo]] can use
 
* 0x10 = Item is the source or target of an [[EarthBound:Timed Item Transformation Table|item transformation]]
 
* 0x20 = "Give" command disabled (cannot move from one character's inventory to another)
 
* 0x40 = Unknown; all built-in items have 0x80 set the same as 0x40
 
* 0x80 = Item disappears after use
 
 
 
==Effect==
 
{{table el|len=2 bytes (0x2)|loc=0x1D-0x1E|valrange=0-65535 (0x0000-0xFFFF), but it must be a valid index in the [[EarthBound:Battle Actions Table|Battle Actions Table]]}}
 
The [[EarthBound:Battle Actions Table|effect]] of using the item.
 
 
 
=="Strength", "Extra Power Increase", "Extra Power", "Special"==
 
{{table el|len=4 bytes (0x4)|loc=0x1F-0x22|valrange=Varies on item's [[#Type|type]]}}
 
These bytes, with their names listed in the order they appear in the ROM, have different effects depending on the [[#Type|type]] of the item. The names are not very accurate to what they do, but they have stuck from when the table was first documented. They are abbreviated as STR, EPI, EPW, and SPE in the following list showing their meaning for different types:
 
Known meanings of bytes 1F-22 for various types. If the type or byte
 
is not mentioned in this list it is either unknown or unused.
 
ITEM TYPE NUMBERS ARE LISTED IN DECIMAL.
